A simple hack using aluminum foil might be the solution for slow Wi-Fi speed. Professor James McQuiggan from Valencia College suggests placing a sheet of aluminum foil behind your router to improve your connection. The foil helps to direct the Wi-Fi signal more effectively, allowing it to travel more freely and avoid unnecessary obstructions.
Research from Dartmouth supports this theory, demonstrating that strategically placing a 3D-printed, aluminum-covered shape can significantly boost Wi-Fi signals in desired areas and reduce them in others. To try this at home, create a “C” shape with a one-foot sheet of aluminum foil, position it behind your router with the shiny side facing outward, and check the connection in areas where you need better coverage.
